I've been collecting for a little over a year now. My wife and myself just moved across the state and aside from injuring myself, I'd say the most memorable moment of the move would be realizing that all the gear I acquired over the past year wouldn’t fit into a 44 gallon bin. Including my PS2 gear, I probably have enough gear to fill two 44-gallon bins. I don’t think that’s too bad for one year.
My gear includes systems/games/accessories from Dreamcast, 2600, NES, N64, PS2, GBA, DS and PSP.
My collection is no more than a drop in the bucket of some of yours but I’m pretty proud of it and I wish I actually had some friends who gave a piss about it. lol.
